KW Owner, any better idea?

I got KWV2 on my car, and now I want to play with it little bit.
Adjusting rebound was quit easy, but I'm having hard time adjusting height of rear.
Is there any easier way to adjust height of rear instead of remove the entire rear spring by disassembling the control arm and shock? I'm not sure how to disassembling + reinstalling later. Also, I don't want to go shop for just adjust rear height tho.. Thanks to KW for great design..

Once your KW's are installed there is no reason at all to remove them to adjust the height (assuming that they were installed correctly in the first place). To adjust the rears all that you have to do is remove your rear wheels and take one of the spanner wrenches that came with your coilovers and turn the threaded spring collar until you reach the desired height that you want. Its very easy to do.

Ya I know, but the problem was top mount strut is not fixed, so the height doesn't change but spring collar and top mount strut just spining together.. that is why some ppl disassembing control arm and take the spring out to adjust height..

I wish I could help you out here, but I really don't know what you're talking about. How aren't the top of the struts fixed? I have adjusted the height on the rear of my car at least five times without having to dissasemble anything. When you spin the spring collar up or down the strut should not spin with it. Are your struts tightened down to spec?

The OP may be making height adjustments without relaxing the suspension bushings.

How do you relax the suspension bushings?
With the wheel off, do you just let the arm hang down (which I would think puts a load on it) or do you support it up (taking the load off)?

We release the bolt at the bottom of the shock to adjust the height in the rear.

I have ST coilovers (close design to V1) and have had no problem adjusting the rear height w/ the included wrench. No spinning issues here, though I've heard of others having that problem.

Does releasing the bolt at the bottom of the shock then allow the suspension to lower further?

try removing the spring because i remember on the right rear of mine i had to sand/grind a little of the spring at the top. theres a sharp edge which probably catches onto the hat and causes a lot of friction. take a good look at the ends of the spring, u may see what i'm talking about.

I've read quite a few post about how hard it's to asdjust the height of the KW coilovers, so I thought I give it a go today on my car. And it was very easy, just like BoostedBMW said.

I lowered them by one turn.

I raised mine... it was a major PITA... the biggest problem is not knowing how much I can raise the rears, since I can't see where the threads end...

And, I had to keep the whole thing from spinning while I turned the height adjustment nut with the spanner wrench...which required very careful coordination!
